Another URL shortening site for the DecodeShortURLs plugin
I just got spam with a short URL http://www.zoodl.com/19714 in it. www.zoodl.com isn't in DecodeShortURLs.cf so its maintainer may want to add it. Martin
[Q] Adjusting Rule Scores - Which file?
Hi, I am interested in raising the score for the rule RDNS_DYNAMIC. However, I cannot find it in any of the files under /etc/spamassassin. I thought that it would be listed somewhere in this directory. In which file is this located? * Why do I want to raise the bar for RDNS_DYNAMIC? I won't use the pbl from spamhaus, nor other expressions that reject email sent from dynamic address ranges. I think if someone [hobbyist] wishes to run his own server and not pay for a static address, then I won't block email from them. However, I would like to add some extra points for sending from one. 99% of spam received here from the dynamic ranges get blocked by postfix for numerous reasons; Some being an invalid rcpt email, some Subjects, RFC compliance, and so on). Regards, S

The stock rules are under /var/lib/spamassassin/3.003001 (or whichever version you have). But don't make changes there, or they will be lost the next time you run sa-update. Instead, add your changes to the local.cf file in your local rules directory (/etc/mail/spamassassin on my system), or create a new cf file to hold your changes. To change the score for RDNS_DYNAMIC, add the following line: score RDNS_DYNAMIC 1.0 Since this directory is read after the main rule directory, anything you put here will override the stock rules. -- Bowie

That rule doesn't appear in any of your local customization files (under /etc/spamassassin) because you've never customized it before.

sa-learn files vs dirs
All other things being the same, which one is faster (maildir here): to feed emails to sa-learn message by message or just provide it with the entire directory?

Directories are faster, you are only running sa-learn once and not once per email.

I played around with this a number of years ago and found it fairly useless in the context of blocking spam. The DROP list isn't meant to be used in such a way because this address space isn't typically the actual source of spam. Instead, the space is more likely used to control botnets, run scans, DOS attacks and other day-to-day operations. The DROP list is best used on routers running BGP in an effort to stop everything prior to a spam run. -- /Jason

date_received for previous hop
Hi list, for some weird reasons... ... I need to know the date where a mail was sent by the previous host (in the mail header chain) to our MTA. From checking HeaderEval.pm I conclude that: (if I'm correct) date_received -> gives me the date where my MTA did accept/take the mail date_header_time -> date where mail was written by some user (MUA) date_diff -> delta of above mentioned values date_diff is (unfortunately) not enough for our specific requirement here... Is there an 'easy' way to get this very specific date of the host one hop back away in the mail headers?
